Hi Simone,

I have exactly as you stated, but found maybe a problem/bug.

1. I put hosted engine to maintenance and powered it off

2. Changed memory in /etc/ovirt-hosted-engine/vm.conf to memSize=8192

3. I restarted both ovirt-ha-agent and ovirt-ha-broker: /etc/init.d/ovirt-ha-broker restart && /etc/init.d/ovirt-ha-agent restart

4. I started hosted-engine and turned off global maintenance.

The hostedengine webinterface still says 4096MB

Now I logged on with ssh and ran the command "free -m"

This command shows:

Mem:          7870       ...

So, I believe my hostedengine was updated, but the webinterface is showing incorrect values: http://screencast.com/t/Bg5xU0Ja

Any idea why web interface is not showing correct value under Defined or Physical memory?

You are not the first that reports that: it seams that it's just a timeout/refresh issue and you have just to wait. Adding Michal here.

 

Regards,

Paul

Hi Simone,

Thanks!

I think I did not restart broker and agent before going out of maintenance mode.

I will try these steps and let you know.

Regards,

Paul

I am trying to change memory of my hosted engine.

I am running oVirt 3.6 with CentOS 6 Hosts with hosted engine on nfs3

We didn't build VDSM and hosted-engine-ha from 3.6 for Centos 6 so basically your hosts are still with oVirt 3.5.

In order to edit the hosted-engine VM on oVirt 3.5, you have to:

1. set global-maintenance mode

2. shutdown the engine VM

3. manually edit /etc/ovirt-hosted-engine/vm.conf on each host (keeping ti coherent is up to you, take a backup)

4. restart ovirt-ha-broker and ovirt-ha-agent services on each host.

5. exits global maintenance mode

Updating to oVirt 3.6 you will be able to edit some parameters of the engine VM from the engine itself.

 

1. I put hosted-engine to maintenance, shutdown vm

2. update /etc/ovirt-hosted-engine/vm.conf 

3. restart vm disable maintenance

Memory is still old value.

How can I change the hosted engine VM?

I did found: http://www.ovirt.org/Features/Hosted_Engine_configuration_on_shared_storage

When I check /etc/ovirt-hosted-engine/hosted-engine.conf there is no 

"conf_volume_UUID" entry.

Do I need to create a shared config volume entry ( conf_volume_UUID ), so I can edit hosted engine VM? If so, how can this be done?

I did try to rerun engine-setup, but this did not trigger anything.

Kind regards,

Paul Groeneweg
